Abstract

Common tapeworms in poultry digestive tracts are called Raillietina species. The present study's objective is to characterize the morphological and genetic relationships between the cestode parasites that infect domestic pigeons (Columba livia domestica) in Saudi Arabia's Al-Qassim Region. Using optical and scanning electron microscopes, the general morphology and surface characteristics of the collected cestode parasites were examined. Using sequences from the ND1 and 18S rDNA gene areas, molecular analysis was used to confirm the taxonomy of this parasite based on its morphological characteristics. This demonstrated a high degree of similarity--up to 98.0% and 74.7%, respectively between the 18S rDNA and ND1 gene regions and other cestode species found in GenBank. Using close ties, phylogenetic research validated the placement of this Raillietina species within Davaineidae. [ABSTRACT FROM AUTHOR]

Abstract

Aphids are common agricultural pests found worldwide and cause significant economic losses to farmers. Although these pests are of economic importance, information on their genome is limited. We examined the sequence diversity of two genes, the mitochondrial gene, subunit I of cytochrome oxidase (COI) and the 16S rRNA-encoding sequence of aphids sourced from tomato farms from two geographical regions of Saudi Arabia (Riyadh and Hafar Al-Batin). Partial sequences of COI (from 12 aphid isolates) and 16S rRNA-encoding sequence (from five aphid isolates) were separately amplified using polymerase chain reaction and sequenced to reveal the genomic similarity among specimens of 92-99% and 95.7%, respectively. Our data did not indicate any differences between aphid isolates. These results demonstrate that the present species are deeply embedded in the Aphis genus and share a close relationship with other Aphis species, including Aphis gossypii as a putative sister taxon. These isolates cannot be categorized as belonging to two different groups with origins in Riyadh and Hafar Al-Batin. [ABSTRACT FROM AUTHOR]
